Following the Miami Heat’s 110-109 overtime loss to the Brooklyn Nets at home Saturday night, Heat big man Hassan Whiteside went on an expletive-laced rant about frustration over his lack of playing time near the end of games.

Whiteside, who finished with 14 points and six rebounds, played just 20 out of a possible 53 minutes Saturday and didn’t play at all in the fourth quarter or overtime period.

The 7-footer didn’t hold back when asked by reporters how tough it is to sit on the bench during the heat of battle.

“It’s annoying,” Whiteside said. “We shouldn’t [go small]. Why are we matching up? We’ve got one of the best centers in the league. Why are we matching up? A lot of teams don’t have a good center. They are going to use their strengths. It’s bull sh*t. It’s really bull sh*t, man.

“There are a lot of teams that can use a center. That’s bull sh*t. I don’t know if it’s because I’m on a minutes restriction. The minutes have been like that all year. It’s really frustrating. It’s been frustrating. It’s tough. I don’t know, man. It’s crazy. I don’t understand it.”

The Heat fined Whiteside Sunday for the rant. The amount of the fine was not announced. The basis of the fine, according to the team, was that his comments were detrimental to the team.

Whiteside has dealt with knee issues this season, missing 28 games. Heat coach Erik Spoelstra saidthe Nets going to their small lineup factored into his decision to sit Whiteside in the fourth quarter and overtime.

“It will get better,” Spoelstra said. “It’s not where it was when he left against Philly, his last game. But game action is game action. You can do all you want behind the scenes. But you got to get those minutes in games. He had some good moments tonight. They went to the smaller lineup and it always comes to that. Does the speed lineup get to size or size get to speed? And their speed got to our size for a little bit.”

Before the Heat PR ended Whiteside’s interview with reporters, he was asked if this season has made him question his future in South Beach.
